A High-Velocity Scatterer Revealed in the Thinning Ejecta of a Type II Supernova

Autor: Leonard, Douglas C., Dessart, Luc, Hillier, D. John, Pignata, Giuliano, Williams, G. Grant, Hoffman, Jennifer L., Milne, Peter, Smith, Nathan, Smith, Paul S., Khandrika, Harish G.

We present deep, nebular-phase spectropolarimetry of the Type II-P/L SN 2013ej, obtained 167 days after explosion with the European Southern Observatory's Very Large Telescope. The polarized flux spectrum appears as a nearly perfect (92% correlation)

A Spitzer Survey for Dust-Obscured Supernovae

Autor: Fox, Ori D., Khandrika, Harish, Rubin, David, Casper, Chadwick, Li, Gary Z., Szalai, Tamas, Armus, Lee, Filippenko, Alexei V., Skrutskie, Michael F., Strolger, Lou, Van Dyk, Schuyler D.

Supernova (SN) rates serve as an important probe of star-formation models and initial mass functions. Near-infrared seeing-limited ground-based surveys typically discover a factor of 3-10 fewer SNe than predicted from far-infrared (FIR) luminosities

A Search for Photometric Variability in L and T type Brown Dwarf Atmospheres

Autor: Khandrika, Harish, Burgasser, Adam, Melis, Carl, Luk, Christopher, Bowsher, Emily, Swift, Brandon

Using the Gemini infrared camera on the 3-meter Shane telescope at Lick Observatory, we have searched for broad-band J and K' photometric variability for a sample of 15 L and T-type brown dwarfs, including 7 suspected spectral binaries. Four of the d

INTEGRAL and RXTE Observations of Centaurus A

Autor: Rothschild, Richard E., Wilms, Joern, Tomsick, John, Staubert, Ruediger, Benlloch, Sara, Collmar, Werner, Madejski, Grzegorz, Deluit, Sandrine, Khandrika, Harish

Publikováno v: Astrophys.J.641:801-821,2006

INTEGRAL and RXTE performed three simultaneous observations of the nearby radio galaxy Cen A in 2003 March, 2004 January, and 2004 February with the goals of investigating the geometry and emission processes via the spectral/temporal variability of t
